Improvement in harvesters



4 UNITED `STATES PATENT OFFICE.

T. H. TAYLOR, OF JEFFERSONVILLE, ILLINOIS;

IMPROVEMENT IN HARVESTERS.

\ Specification forming part of Letters Patent No. 95,537, dated October 5, 1869.

To all whom it may concern:

Be it known that I, T. H. TAYLOR, of Jeffersonville, in the county of Wayne and State of Illinois, have invented a new and useful Improvement in Reaping and Mowing Machines; and I do hereby declare that the following is -a full, clear, and exact description thereof,

which will enable others skilled in the art to make'and use the same, reference being had to the accompany'llg drawings, forming part of this specilieation.

This invention relates to improvements in reaping and mowing machines designed to provide an improved arrangement for operating the cutter-bars, also an improved arrangement of the cutter and cutter-supporting' bars, all as hereinafter more fully specified.

Figure 1 represents a longitudinal sectional elevation ot' my improved machine, and Fig. 2 represents a transverse section of the same.

Similar letters of reference indicate corresponding parts.

I propose to employ two cutter-bars and two sets ot' cutters, one above the other, andarranged to move simultaneouslyin opposite directions, similar to others now in use.

For imparting the said simultaneous movements in opposite directions I employ a driving-wheel, A, having a wide rim projecting toward the cutting devices from the web of the wheel, and having on its inner surface two sets of inclined projections, B and B', arranged to throw alternately in opposite directions; and I provide a connecting-rod, C and O', for each cutterbar, having friction-bowls attached to their inner ends and supported by springsupportsD D in the path of the projections B B', one suciently above the other to be in contact with one of the projections B throwing in one direction, while the other is in contact with one of the projections B throwing in the other, thus producing the simultaneouslyopposite reciprocating motions.

My improvement in the cutter-'bar support and the cutter-bars consists in constructing the former ot' two parts, a, ot' sheet metal, bent, as represented in cross-section in Fig. 1, to form grooves in each part for the cutter-bars, and uniting the two parts by blocks b between them at the rear, and to which they arc sceuredby screws, also, in shaping the cutterbars in the parts d to tit the said grooves in the cutter-bar support for forming the guides wherein they reciprocate, and tting theln with dat surfaces each side of the grooves to work on each other. This arrangement of the cutter-bars and their supporting-bar enables me to tit them by simply. passing them through shaping-rollers having grooves suitably formed. It also provides stronger and more durable bars.

Having thus described my invention, I claim as new and desire to secure by Letters Paten t- 1. The combination of the driving-wheel,

having the projections arranged as described,

with the connecting-rods suspended relatively thereto, substantially as speciled.

2. The cutter-bar supports, formed of two parts, grooved for the vreception of the cutterbars, and united substantially as described.

T. H. TAYLOR.
